My 1.2 Celeron

[snow patrol]

ok guys, realised we were kinda hijacking someone elses thread there. Any way, for those not following the other thread:

- Intel Tualatin Celeron 1.2Ghz
- Abit ST6
- 512megs crucial cas 2

UPDATE: - Just because I couldn't resist it, I obviously had to play around with the board fsb wise. I'm waiting for my geforce 3 to arrive tomorrow though, before installing 3dmark and the like, so no stability tests until then. Any way, I'm writing this at 1.61Ghz (134 first bus speed i tried!). Sandra is showing chip temperature at 47 c, which is perhaps a bit high...but I'm only using a fop 32 and ystech at the moment so. Hoping to get 1.7ghz at 42 degrees or under eventually :)

Here's the last thing I posted in his thread, about mbm5:

ok guys, got it all up and running with my fop 32. Haven't overclocked yet, installed xp and motherboard monitor.

However, how do I get motherboard monitor to show me core temps?? It's showing me all my voltages, but sensors 1 2 and 3 are just all showing 0 degrees.

With my last mobo i just used asus probe, so I'm not up to scratch on mbm 5.




Anyone help with the mbm issue?

ok, now for a slight annoyance:

When I have the fsb at 133mhz, it freezes while booting. This is because of my usb intellimouse explorer, which starts flashing red like crazy. When i remove the mouse, windows loads fine. The PCI divider is definitely set as 1/4..

Also, why is it that when I set the cas to 2 in the bios, it shows as being 3 on boot up, yet when I set it as 3 in the bios it's 2 in bootup. Is this just a bug (like the dodgy mhz speeds shown at bootup ;))

Another thing I'm not keen on, is that everytime you push it too far, or try a setting which results in failure to bootup, you have to reset the cmos.

My Asus P3V4X was great because you just needed to power down, then boot back up and it would automatically remember your last good settings. Is there no way to do this on the ST6??

Any way, can't wait for my geforce 3 to arrive (tomorrow or monday), then I can get down to some real tests :) using an 8meg rage pro at the mo....:rolleyes:

Nice overclocking dude..
Damn :)

Did you use the wire trick ? Maybe it needs a big more voltage to boot at those high speeds.


Good Luck on your 3dmark benchies.

Congrats on the first attempt successful OC to 1.6+ Ghz!

My gosh.. you'll be loaded with goodies! a T-Celery 1.2 to a New mobo to a GF3! you must be excited. I want a new vid card.

About the MBM5, go to "settings" from the MBM5 icon in the taskbar. Select "temperatures". Next to the "Should display board sensor", select one of the sensors with the Diode displayed. Then update the setting and see if the CPU temp will properly register. If it doesn't, try other Diode ones. It worked that way with my BE6-2 rev 1.2 mobo. I donno how it may work with yours though but try.

Showing CAS2 or 3 when you boot.. do u mean does your BIOS recommends the CAS setting at those number? it shouldn't change the CAS setting by itself even the system is overclocked. I know that my Iwill KK266R mobo however, does control the amount of RAM to a lesser amount by using one stick instead of two are on the board when overclocked severely, but the CAS settings didn't change itself, but then again.. I don't know how your mobo works for sure.

No, I dont' think you'll have to reset the CMOS everytime when the system fails to boot due to OC'ing reasons or etc.. Resetting the CMOS maybe needed if necessary. Even with your ST6, you should be able to unplug the power cord for 10- 15 sec and then plug back on and turn the system back on appropriately. This does usually happen to me at least..

Thanks mate, I think I've got the right temp thing, although there doesn't seem to be any difference between my idle and load temps. This is at default speed again...about 35 degrees c.

Might worry about this more when i get my sk6 in.

The cas thing, it just seems to be 'showing' the oposite of what I select, but only in the boot up. Maybe ol' man will be able to shed some light on this one.

btw, yes i did the wire trick and have full voltage selection from 1.025 - 1.8

Wish i could get it up to 2.0 :D

2.0!!!, lol... :p :D well the SK-6's cooling performance is almost close to water cooling(yes amazing..) who knows maybe with a bad azz air blower Delta 50+ could shove to handle 2.0! lol me thinkx.. Hopefully Ol'man will get here shortly and see what he'll say hehe.

[snow patrol]

well, i've put her at 1.2 again and 1.4v, because I want to wait for my SK6 before shooting really high. Off out now to work, await ol'man's reply ;)

Hey man I told ya these things get hot eh! Also you need a good PSU. I am installing a second ATX psu today instead of the AT PSU I have in here right now. I am guessing at these speeds these things are producing about as many watts as some of the lower running athy's. Many times you may think it is cpu failure but it is not and simply the PSU is not strong enough. I have a 300w ATX that I though would last me forever. Yeah right these two 120's suck the juice as also my cpu by a very large amount and my PSU won't even boot my system. More than anything;) I am going to hook up my other ATX PSU to run every thing except the MOBO. That will give my CPU as much power as it needs.

If you have cas2 ram but set it to cas3 in the bios it will suggest you to set it to cas2 upon boot every time. If you have cas3 and set it to cas2 it will say the same thing.

Have you noticed that your chip gets flaky around 50 deg .C. RIght now I would concentrate on getting it stable at 1.6;) That is a 33% OC and not bad at all especially when we are dealing with 12x multi's.

My advice is;

1.) Make sure your psu has enough juice to power it.(350~400w)

2.) Make sure you have good case ventilation.

3.) Do not let temps get over say 45 deg. C.(42 deg. C is ideal at load I found out. Also I couldn't achieve this without removing the IHS but that is me. Maybe you got a better chip.)

4.) If you are only getting to 1.8v then you could try some nail polish on vid1 to disable it and then connect 0,3,25 to get to 1.825v. I need that little extra right now.

Answer some questions for me and I will tell you how much potential your chip has got.

A.) What was your vcore at when you boot?

B.)Are you setting it to 132fsb or 133fsb in the bios cause if it is at 133fsb it in reality is at 134fsb. You may want to try 132 for the time being to do the 133. WCPUID says mine is at 133 when I set it too 132 so I believe it to be true. That is the way these mobo's seemed to have always been, they overclock beyond defualt automatically.




Last comment, I would not try to OC that thing much more until you have good cooling(ie. the SK6 arrives.)

Thanks a lot for the comments Ol man. A few points:

- My PSU is just a 'standard' 300W one that I got 2 years ago with my pretty rubbishy case. There's no fans in the case at the moment, but I have a couple of 80mm arriving, so I plan on doing a little modding to get some fans in, and maybe a 60mm on the back of the case pushing air out? I take it the fan(s) on the side of the case should be sucking air in?

I may consider a sparkle 400w PSU as my next upgrade in that case...

Also, I have a couple of rounded IDE cables arriving which should help sort out some congestion in there.

At the moment, as I said, I'm leaving things at 1.2Ghz with 1.5v of juice. Just as a tester, I managed to load windows fine at 1.725v at 1680Mhz, so I'm hoping for pretty good things from this chip, BUT, I will wait the few days it will take for my cooling stuff to arrive, just to be on the safe side.

If necessary I will try, the nail polish to get a bit of extra voltage - are there any links at all to pictures of how to do this?

Also, it's not that the BIOS is 'suggesting' what I set my RAM to...it's just then when I HAVE set it to cas 2, at the boot up screen, it's showing 'ram cas percharge (or whatever ;)) at 3), but when I SET IT as 3 in the BIOS, it shows it as being 2. Will try RAM benching to determine what's going on there though, so shouldn't be a problem.

So yeah, any comments on how to best ventilate my midi tower would be much appreciated, ta :)

1680MHz on 1.725v. You gots a good chip and you possibly won;t need to take off the IHS unless you want to hit higher;)
